We could exercise some google-fu:

According to our own Andrew de Quincey:

Kindle 3 hacking
My latest gadget is a kindle 3, and of course I want to hack it.
...
It seems to be a remarkably straightforward linux install. The main kindle applications are all implemented using a normal Java VM (Sun's "C" Virtual Machine (CVM).

So, let's investigate "Sun's CVM":
http://en.wikipedia.org/wiki/CVM

C virtual machine, a Java virtual machine distributed by Sun Microsystems and used on mobile devices such as the Amazon Kindle

And the official "basic use of cvm" guide:
http://docs.oracle.com/javame/config...ml/running.htm

The CDC Java runtime environment includes cvm, the CDC application launcher, for loading and executing Java applications. This chapter describes basic use of the cvm command to launch different kinds of Java applications, in addition to more advanced topics like memory management and dynamic compiler policies.

The official "cvm reference" might come in handy:
http://docs.oracle.com/javame/config...e/html/cvm.htm

This appendix describes the cvm command in detail. For the Oracle Java ME Embedded Client, see the Oracle Java Micro Edition Embedded Client Reference Guide for detailed information about cvm for the Oracle Java ME Embedded Client.

Digging deeper, here is the "cvm bootstrap and initialization process":
http://weblogs.java.net/blog/jiangli...bootstrap.html

You probably already know that CVM is written in C. So what happens from the VM's launched (invoking the C main() function) all the way till the first line of Java code in your main() method is executed? There is a lot going on during that period, and we usually refer to this as the VM bootstrap. This article will explain the details of the CVM bootstrapping and initialization process.

can I customize the order of the dictionaries
I can only find a setting to control which dictionary showed first

Since it says that there is nothing to setup, that would mean that you can't customize it either. Until ixtab extends the functionality you probably can't do anything. Unless you are experimenting with maybe renaming the dictionaries?

So it is possible to install and unintall it without jailbreak? Just copy the file to the Kindle and reboot?

//EDIT
Damn. Missinterpeted it. Native language isn't english... -.-

It is possible to copy the file and reboot, but without the jailbreak the installation will fail. Jailbreak is required for installation / removal and during the use.

@weatherje: Read the first post again, particularly that half-sentence clearly stating "that the jailbreak is required". Read the README. And then read your post again.

ohhhhhh. Sorry sorry. My native language isn't english and I missinterpreted this sentence... I thought it means, that it works without a jailbreak, but it means something completely different.
Sorry for that.

Changed the sentence to "Of course, the jailbreak is required." to avoid such confusion in the future

Hi, I created a Minecraft-Mod-Loader from your PatchingClassLoader

Are you ok with this?

Of course! Good to see that the idea is considered useful

And thanks for sharing the info

Sorry if this may sound silly but is the UI necessary or optional? I am on a PW and all that matters to me is the hyphenation support.

Thanks!

I't optional but IMHO strongly recommended. Its unintrusive, doesn't modify any menu and make it very easy to enable/configure/disable features. You simply access it as if it were an active content (it's listed together with the books). And if you try it, you will also love the margin modify feature.

Hi,

The latest version of JBPatch is 3.1.0, will it work with newer KT with firmware 5.3.2?

My KT has firmware 5.1.2 with latest JBPatch & Collection Manager, can I upgrade to KT's firmware 5.3.2?

Or do I need to uninstall all these and then upgrade to newer KT firmware?

TIA

1) No, neither of the 2 versions 3.1.0 fw510 or fw531 will work with KT 5.3.2 (see first post) - you have to wait for a new version for the KT 5.3.2, and even then it is very likely that only those features supported by PW will also be available on KT 5.3.2

2) I believe you have to uninstall both, JBPatch and CM. It won't hurt anything, the update will simply fail if you don't uninstall them. But since both won't work any more even if they survive the update, you should uninstall them anyway. DO NOT uninstall the jailbreak itself, or you won't have the KT jailbroke after the update. There is a new version of Collection Manager that will work on KT 5.3.2

Edit: *Answered my main question with some Googling :P*

One question though, whats the Kindlet JB do? The actual jailbreak install dev certs (i think?), but not sure what the Kindlet JB is. :x And if I decide to update, do I need to remove the Kindlet JB first?
